What is a Network

Network Protocols

Aside from the issues of the physical network (signal types and voltage levels, connector pinouts, cabling, topology, etc.), there needs

Synchronous Counters

A synchronous counter, in contrast to an asynchronous counter, is one whose output bits change state simultaneously, with no ripple. The only

four bit up counter timing diagram

Asynchronous Counters

In the previous section, we saw a circuit using one J-K flip-flop that counted backward in a two-bit binary sequence, from 11

D latch ladder logic

D Latch

Since the enable input on a gated S-R latch provides a way to latch the Q and not-Q outputs without regard to

Gated S-R Latch

Gated S-R Latch

It is sometimes useful in logic circuits to have a multivibrator which changes state only when certain conditions are met, regardless of

Gated S-R Latch

S-R Latch

A bistable multivibrator has two stable states, as indicated by the prefix bi in its name. Typically, one state is referred to as set and the

Karnaugh Mapping

Introduction to Karnaugh Mapping

Why learn about Karnaugh maps? The Karnaugh map, like Boolean algebra, is a simplification tool applicable to digital logic. See the “Toxic
